I don't think its important to guarantee that exactly the same audio 
results from playing a particular MIDI stream on different systems.

Many more application scenarios are possible if browsers allow their 
users to decide which of their installed MIDI output devices they want 
to use, by listing them in a preferences dialog. On Microsoft OSs the 
"Microsoft GS Wavetable Synth" would appear there, and would be the 
default synthesizer. But if I've got a better piano installed, then I 
want to be allowed to use it. If I want to link up with a lighting 
system, then I want to be able to do that. If I've got the Vienna 
Philharmonic installed, I may want to use that.

So even if there was a common default synthesizer across all browsers, 
there's no guarantee that users would actually be using it.

Exactly.

I don't think its too much to ask of an operating system, that it should 
supply a default software synthesizer in the way that Microsoft does. 
Perhaps Microsoft could  be persuaded to make their's open source... :-)
